DEVICE FOR CUTTING SLEE'Iv FROM TROLLEY-WIRES.

Specification of Letters Patent. Patgntgd Gret 10, 1911,

Application filed April 29, 1910. Serial No. 558,481.

To all whom it may concern:

Be it known that I, EUGENE SLIXGL'UFF, a citizen of the United States. residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Devices for Cutting Sleet from Trolley-\Yires, of which the following is a specification.

My invention relates to devices for cutting the sleet from trolley wires.

v The object of my invention is to provide a simple, efficient and inexpensive device which may be easily fastened to or detached from the trolley harp without removing,

the trolley wheel for removing the sleet and ice from the trolley wire.

My invention consists broadly of two clamping plates having a rotating cutter mounted between them, and a boltadapted to'clamp the trolley wheel between said plates.

My invention also consists in certain novel features which will hereinafter be setforth and claimed.

In the drawing which serves to illustrate my invention: Figure 1 is a side elevation of a portion of a trolley'pole and trolley harp showing the trolley wheelin place and also showing my improved cutting device mounted thereon. Fig. 2 is an isometric view of my improved cutting device.

' Fig. 3 is an end elevation of my improved trolley cutter. Fig. 4 is a fragmentary sectional view taken on the line 4 i of Fig. 1.

Referring more particularly to the drawing, I show at 1 a fragment of a trolley pole 1 having a trolley harp 2 mounted thereon. The trolley harp 2 is of the ordinary construction and forms no part of my invention.

3 illustrates the usual type of trolley wheel having spokes 4c therein.-

My improved device for cutting the sleet from wires consists of the plates 5 and 6 which are adapted to clamp the trolley wheel 3 therebetween. On the lower side of the plates 5 and 6 I provide lugs 7 which may be of any particular shape or size and are adapted to engage the top of A bolt 9 is provided which passes through suitable openings in the plates 5 and 6 and also through the trolley wheel 3 between its spokes 5L and is provided at one-end with a wing nut 10 and lock washer 11.

The plate 5 may be provided with a bead or raised portion 12 alongside of the openthrough which the bolt 9 passes to prevent the bolt from turning. Placed between the plates 5 and 6 upon a shaft 13 I provide 5 a rotating cutter 14 which is preferably corrugated as shown in Figs. 3 and 4 to form cutting edges 14, the corrugations running something after the manner of spiral or screw threads. The plates 5 and 6 may be strengthened by bosses 15 to allow the shaft 13 better bearing surface and I provide preferably cotter pins 16 to hold the shaft 13 in proper position. Recesses 17 may be placed in the bosses 15 in order that the cotter pins may not project outside the surface of the plates 5 and 6 and thereby give the device an ugly appearance.

My improved device may be mounted upon the trolley harp and trolley wheel so very easily. It is simply necessary to place the device in the proper position upon the trolley harp and trolley wheel and then insert the bolt 9 and tighten the plates upon the wheel by means of the wing nut 35 10, a lock or spring washer being provided in order to lock the wing nut. Thus, when the trolley is raised to come in contact with the Wire the cutter 14: will correspond to the trolley wheel and as it rotates the trolley 9 wire will pass from side to side between the plates 5 and 6 and at the same time'the corrugations of the cutter 14 will thoroughly clean the wire of all sleet or ice.

If it is desired, an arrow 18 may be upon the plate 5 in order to insure the plates being mounted upon the trolley harp n the proper manner, the arrow pointingin the direction of motion of the car.

In Fig. 1 I illustrate the device mounted upon the trolley pole and in engagement with the trolley wire 19.

It will be observed that the plates 5 and 6 are provided with a slanting surface or edges 20 and rounded edges or surfaces 21 on the forward end of the device. This is done to prevent the device from impairing the wires in case the trolley should be accidentallyd i'sengaged from the wire.

The cutter 14 is preferably made of a soft malarial, each as brass, in (:ial 110i; injure The Wire. llhiz z of lhe Pal er Lil such tl'iat i again ils baa/rm is reversible, it being imma ial 110W 5 the saline is n'inunted and it will (i; ate aml .I'QXHU"Q the :s from the wire W l Many mailiilcz'alicms my 11mm mi may a Wllllfilli; (lG'JfiJ'llll "win its Sylvia: e, and. l (l0 not mm. in be confined 12am; details Slum i i ll claim new (l desire to Mrs Patent is:
